CONSTRUCTION OF BATTERIES AND ELECTROLTIC APPARATUS.

Specification of Letters Patent.

Patented Aug 1 1, 1908..

Application filed February 11, 1905. I Serial No. 245,223.

iTo al-l whom it may concern: Be. it known that I, FRANK A. DECKER, a =c1treen of the United States, residi'n'g at "Philadelphia, county of Philadelphia, and

State of Pennsylvania, have invented certain Improvements in the Constructlon of Batteries and Electrolytic Apparatus, .of

which the following is a specification.

The primaryv object of my invention is to provide an insulating seal which will retain, without being affected thereby, the sol1itions employed in batteries and electrolytic apparatus, and by the use thereof to effectively hold 'together parts producing a sys' line 2-2 of Fig. 1: Fig.3 represents a per-.

spective view, partbeing broken away for t e purpose of illustration, showing a group of plates or diaphragrns assembled and sealed together to form liquid holding comartrnents in accordance with my invention: ig. 4: represents a sectional view taken on the line 4+4 of Fig. 3: Fig. 5 represents a perspective'view of a broken section of a cell showing the parts sealed together in accordance with my invention: Fig. 6 represents a perspective view of a second form of cell constructed in accordance with my invention, parts being broken away for the' purposeof illustration: Fig. 7 represents aperspective view in vertical section taken on the line 7-7 of Fig. 6: Fig. 8 represents a sectional elevation taken through part of the cell and a conduit for changing a fluid used therein: and Fig. 9 represents an elevation of acorner of a plate or diaphragm adapted for use, in the present improvements, being a portion of the flanged plate shown in Fig. 7 with the bushing removed.

In the views shown in Figs. 1 and 2, the

diaphragm represented comprises four sections, 1 2, 8 and 4, suitably of earthenware or carbon, sealed together on the lines 5-5 and 66 by means of the registering, parallel, angularly arranged grooves or sockets 77, having rubber 8 packedand vulcanized therein, and the; registering," parallel,

angularly arranged grooves or sockets 99,l

having rubber I0 packed and" vulcanized of the original body.

therein, the joints being made by clamping the sections firmly togetherin registration after the corresponding grooves have been packed and then heating the plate or portions thereof to be secured to ether to form solution contamers. The several sections are provided with the bordering flanges or ribs 1 2 3 and 4 for stren thening and spacing thestructure, and with the strengtheningribs 1, 2", 3 and 4 joined together sons to support the thin porous diaphragm body produced preferably by removing part In the viewsshown Figs. 3 and 4, the

diaphragnis 11 are arfarigml in parallel posi v tions. to bring the bordering flanges 11 toparallel, angularly arranged groovesgnjor;

'gether in registration so as to form the coin-f artments or containers 12, the several sockets 11 'containing rubber l3 packedand vulcanized therein, the V filled with rubber after which the plates arranged to bring the grooves int-o registration and there clamped together during v'ul CfiIllZ fittlOIl. In the "-view shown in suitably of rubber or porcelain; is provided with the dove-tail groove or socket 15 forre ceiving the envelop 18; suitably of'lead, thegroove havingsthe rubber 17 packedtherein and vulcanized so that it securesthe envelop and seals the joint between itv andthebase,-

the holes 17 being formed in the portion of the envelop contained in the groove so-that the rubber will work thereth-rough and firmly bind the parts together. The 'rece-ptacleorcontainer thus formed receives the diaphragms 1 8 having the reinforcing and sp acin flanges or ribs 18thereon which are arranger in parallel relation so as toforrn the compartments 19. .To seal these compartments the' bottom flanges 18 are connected together by the rubber joints or seals 20, in the manner described in connection with Figs. 3 and 4,.

and the side flanges are provided with exterior grooves or sockets 18 having the rubberpacked therein and vulcanized thereto 2 and to the envelop 16, to form sea'lsproducf m In Figs. '6 to 9 inclusive, there'is-show'n a .cell construction having a vulcanizedrub'b'er envel'op 21 containing cups formed-by join-' ing' together the diaphragms '22, with their.

bordering flanges .22 :in registration, so as to form the compartments 23. The 1jespecgrooves being first leak proof containers or compartments.

. tion during the vulcanization oi the rubber. I

' In the botton'rllanges of the plates are formed.

(ill

the sockets intersecting the grooves 22 and having the irregular recesses 25 therein. These sockets are joined together, in registrationE-to form a seat foia rubber bushing 26 whiclris vulcanized therein integrally with the rubber 24 and held by its penetration into the recess 25. Secured to the bottom of the envelop 21 is a rubber conduit 27 which is provided \With a socket 227', the interior of the cup being connected with the interior of the conduit by screwing the hollow nipple 26 into the bushing and socket so as to firmly connect them together and provide an insuating leak proof passage therethrough. The conduit 27 communicates by a passage 28 leading therefrom through the bottom of the envelop or container to the pipe 29, the bottom. having a socket 21 therein for receiving the branch 12? of the .iipc which is secured by the rubber3l) packed. and vulcanized in the socket to engage the flange on the branch and seal the joint. The pipe, Whose exterior body portion is suitably of lead, has the rubber lining :29 formed by. eXpz'inding soft rub ber therein and vulcanizing it to form an interior seal throughout the pipe for changing the fluid in the cups. A second fluid, contained in the space or spaces exterior to' the cups, can be changed. by means of the rubber conduit 3] having the aperture 31 communicating therewith and connected with a rubber lined pipe 32 as by the connection between'tho conduit 27 and pipe 2%).
